The electric field at the origin is along the positive x-axis. A small circle is drawn with the centre at the origin, cutting the axes at points A, B, C and D with coordinates (a, 0), (0, a), (-a, 0), (0, -a), respectively. Out of the points on the periphery of the circle, the potential is minimum at
(a) A
(b) B
(c) C
(d) D
digAnsr: a
Ans : (a) A
The potential due to a charge decreases along the direction of electric field. As the electric field is along the positive x-axis, the potential will decrease in this direction. Therefore, the potential is minimum at point (a,0).
